The Hermite curve with four control points P0(0,0), P1(1,1), P2(2,-1), and P3(3,0) has tangent vectors P0'(1,1) and P3'(1,1) at the endpoints. To determine the intermediate points on the curve at t = 1/3 and t = 2/3, we can use the Hermite interpolation formula.

The Hermite interpolation formula allows us to construct a curve based on given control points and tangent vectors. In this case, we have four control points P0, P1, P2, and P3, and tangent vectors P0' and P3'.

To find the intermediate point at t = 1/3, we use the Hermite interpolation formula:

P(t) = \((2t^3 - 3t^2 + 1)P0 + (-2t^3 + 3t^2)P3 + (t^3 - 2t^2 + t)P0' + (t^3 - t^2)P3'\)

Substituting the given values:

\(P(1/3) = (2(1/3)^3 - 3(1/3)^2 + 1)(0,0) + (-2(1/3)^3 + 3(1/3)^2)(3,0) + ((1/3)^3 - 2(1/3)^2 + (1/3))(1,1) + ((1/3)^3 - (1/3)^2)(1,1)\)

Simplifying the equation, we can find the coordinates of the intermediate point at t = 1/3.

Similarly, for t = 2/3, we use the same formula:

\(P(2/3) = (2(2/3)^3 - 3(2/3)^2 + 1)(0,0) + (-2(2/3)^3 + 3(2/3)^2)(3,0) + ((2/3)^3 - 2(2/3)^2 + (2/3))(1,1) + ((2/3)^3 - (2/3)^2)(1,1)\)

Calculating the equation yields the coordinates of the intermediate point at t = 2/3.

In this way, we can use the Hermite interpolation formula to determine the intermediate points on the Hermite curve at t = 1/3 and t = 2/3 based on the given control points and tangent vectors.

Step-by-step explanation:

A quadrilateral is a four sided figure. So, the base of the quadrilateral pyramid has four sides. It also has 4 edges and 4 bases

sum of edges = sum of base edges + sum of lateral edges

1cm = 10mm

55mm = 5.5cm

sum of base edges : 5.5 x 4 = 22cm

Step-by-step explanation:

Matt drinks water 12 times on his bike ride and eat snack 4 times.

Let us assume that Matt drinks water m times and eat snack n times.

Here, Matt bikes 25 miles, take a short break, and then bikes another 11 mile.

This means that onnhis bike ride he traveled total 25 + 11 = 36 miles.

Matt drinks water every 3 mile.

So, by unitary method,

m = total distance / 3

m = 36/3

m = 12

This means that he drinks water 12 times.

And he eat a snack every 9 mile.

So, by unitary method the value of n would be,

n = total distance / 9

n = 36 miles / 9 miles

n = 4

This means that he eats snack 4 times.

Inverse means to revere something which has been done earlier. An undo operation in mathematics is the operation of undoes what was done by the previous operation.

For example suppose the given expression is no 5. Then by adding 4 and again subtracting 4 keeps the system isolate.

Hence the property of equality which is needed to isolate a variable and solve a given equation is use inverse relationships to "undo" the operation. Thus the option A is the correct option.

The cost will be $627,000 for about n = 59 units made.

We know that the polynomial function:

C(n) = 3n^3 - 4n^2 + 250b + 75,000

Gives the cost of producing n products.

We want to find the value of n, such that the cost is $627,000

So we need to solve the cubic equation:

3n^3 - 4n^2 + 250n + 75,000 = 627,000

Now we can subtract 627,000 in both sides to get:

3n^3 - 4n^2 + 250n - 619,500 = 0

And now we can graph that equation and find the intercepts:

There you can see that the intercept is at n = 59, so that is the answer.

Answer:

6 in = 80 miles

Step-by-step explanation:

Given that:

Distance between Capeton and Jonesville = 80 miles.

Map scale : 0.75 in = 10 miles ; this means 0.75 inches on the map represents 10 miles on land.

Hence, If ;

0.75 inches = 10 miles

x inches = 80 miles

Cross multiply :

10 * x = 80 * 0.75

10x = 60

10x / 10 = 60 / 10

x = 6 inches

Hence,

6 in = 80 miles

To solve the expression (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · [18 + 3 · (13 - 9) - 5], we follow the hierarchy of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

By applying this hierarchy, we can simplify the expression step by step to find the result.

Following the hierarchy of operations, we start by simplifying expressions within parentheses and brackets.

First, within the brackets, we evaluate the expression (13 - 9) which equals 4. Therefore, [18 + 3 · (13 - 9) - 5] becomes [18 + 3 · 4 - 5].

Next, we evaluate the multiplication within the brackets: 3 · 4 equals 12. Thus, [18 + 3 · 4 - 5] simplifies to [18 + 12 - 5].

Moving outside the brackets, we proceed with addition and subtraction: 18 + 12 equals 30, and 30 - 5 equals 25. Therefore, [18 + 12 - 5] becomes 25.

After simplifying the brackets, we can now evaluate the remaining expression: (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · 25.

Within the parentheses, we perform addition: 42 + 20 equals 62. Thus, the expression becomes 62 ÷ 4 - 2 · (9 ÷ 3) - 2 · 25.

We continue by evaluating the division: 62 ÷ 4 equals 15.5. The expression now becomes 15.5 - 2 · (9 ÷ 3) - 2 · 25.

Next, we perform the division within the parentheses: 9 ÷ 3 equals 3. The expression becomes 15.5 - 2 · 3 - 2 · 25.

Finally, we evaluate the remaining multiplications: 2 · 3 equals 6, and 2 · 25 equals 50. The expression becomes 15.5 - 6 - 50.

Continuing with the subtraction, we have 15.5 - 6 equals 9.5. Therefore, the final result of the expression (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · [18 + 3 · (13 - 9) - 5] is 9.5.

Answer:

To show that two fractions are reciprocals, you can multiply them together and check if the product is equal to 1. That is, if we have two fractions a/b and b/a, their product is:

(a/b) * (b/a) = ab / ba = 1

Therefore, if the product of two fractions is equal to 1, they are reciprocals of each other.

For example, let's say we have the fractions 2/5 and 5/2. We can multiply them together to check if they are reciprocals:

(2/5) * (5/2) = 1

Since the product is equal to 1, we can conclude that 2/5 and 5/2 are reciprocals of each other.

120.39% increase in the volume of the cylinder.

Solution:

Let the radius of the original cylinder = r cm and height = h cm.

Original volume = πr²h

New radius of cylinder after increase =  \(\frac{110}{100} r = 1.1r\\\)

New height of cylinder after decrease = \(\frac{99.5}{100}h = 0.995h\)

Now, new volume of the cylinder =  π × (1.1r)² × 0.995h

                                                        = 1.2039πr²h

Step-by-step explanation:

I am not sure what you mean. you don't round the intermediate numbers and results. only the final result.

you keep the irrational terms (like square root) like variable terms as they are and apply operations on them without actually expressing them as numbers.

only at the very last moment (when the final result is calculated) would you express them as actual number. and then you round the final result.

so, this is solved via Pythagoras :

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.

in our case we have

BP² = BN² + NP² = 7² + sqrt(95)² = 49 + 95 = 144

you see ?

no need ever to bring the actual result of sqrt(95) into the picture. just keep it at sqrt(95) and do with it, what you would do with any actual number.

BP² = 144

BP = sqrt(144) = 12

so, we never had to deal with the actual irrational number.

we know how it is created, so we keep using that term to represent it.
